Generate text embeddings and semantic embedding vectors using OpenAI text-embedding-3-small for vector search, semantic similarity, clustering, retrieval, and RAG workflows.

ZenSched `timesheet_status` — Shift-pair timesheet status for a period: complete/open, hours, GPS, approval/lock flags, pending edits. period: YYYY-MM, YYYY-MM-DD:YYYY-MM-DD, current (payroll window), or blank (calendar month). Optional worker_id, worker_ids_json, event_id. level: 0/1/2 vendor approval level (default 0 = approved_0). Pay-per-call $0.01 USDC; the paying wallet owns the org (auto-provisioned on first call).

Venice Responses API (beta) — OpenAI-compatible structured agent outputs with typed blocks (reasoning, message, tool calls), paid per request in USDC on Base via x402, no API key. No x-venice-responses-mode header → Venice default (OpenAI models native; Venice-only extras stay on

Detect upgradeable proxy patterns (EIP-1967, UUPS, Transparent, Beacon) for any contract and return the current implementation address. Essential before trusting or calling an unknown contract.

[MCP: optimize_context] Pay-per-call JSON context pruning & LLM token budget enforcement. Saves up to 85% prompt tokens.

Verify one legal citation. Body: {"citation": "<string>"} - full ("Miranda v. Arizona, 384 U.S. 436 (1966)") or bare ("384 U.S. 436"); the case name enables mismatch detection. Deterministic: regex plus cache / local corpus / CourtListener, no LLM in the path. status=verified (name confirmed), suspicious (reporter resolves to a DIFFERENT case - the fabrication signature), or not_found. verified=false is a finding, not an error: do not retry. Only verified results are cached.

Institutional (13F) ownership & flow for a stock (?ticker=<stock ticker>)

Converts caller-supplied MIDI-note sequences to adjacent pitch intervals, forms fixed-length interval n-gram sets and reports Jaccard overlap. It does not analyze rhythm, harmony, timbre, recordings, access to prior work or legal substantial similarity, and cannot determine plagiarism.

Extract clean, boilerplate-free readable text from one known public HTTP(S) URL for LLM research or RAG ingestion; private, local, authenticated, paywalled, or blocked resources are not supported. USE WHEN: agent already knows the URL and needs clean page text. DO NOT USE WHEN: agent needs web search, multi-page research, comparison, structured web workflow, or change detection. USE web-intelligence FOR: those broader live-web operations.

Crypto staking rewards: live staking APY and TVL for liquid-staking and restaking protocols (Lido, Rocket Pool, ether.fi, Jito, Binance, …), ranked by size. Filter by asset (e.g. ETH, SOL), chain or protocol. Data source: DefiLlama.

Downloads one HTTPS image through the hub SSRF guard, then asks the configured OpenAI vision model for strict structured JSON. It reports observed features and readable markings, at most five ranked type candidates, and conductor material, core count or cross-section only where the image supports them; unknown values remain null or unknown. The result is identification assistance, not an electrical safety clearance, approval, voltage-state determination or substitute for inspection and testing.

Total value locked (USD) for a DeFi protocol (e.g. "aave") or a whole chain (e.g. "Ethereum"). Provide exactly one of `protocol` or `chain`.

Validates frame/channel dimensions, clamps weights to 0–1 and applies exponential smoothing over time in each named channel. It does not infer a face, build a rig, retarget skeletons, process video or replace animator review.

Use when an agent needs x402 capability tags with demand. Returns tag vocabulary: every capability tag with its provider count, 30-day paying wallets and median price

DNS Lookup API. Resolve domain DNS records and receive structured JSON with A, AAAA, MX, NS, TXT, CAA, and SOA records. Useful for agents, developers, domain diagnostics, email setup checks, DNS troubleshooting, and infrastructure investigation. Paid per call via x402.

Current U.S. nuclear power outage levels, updated daily: nationwide total generating capacity, megawatts offline, and percent outage. Aggregate figure for the whole U.S. reactor fleet, not broken out by individual plant or reactor. Sourced from the U.S. Nuclear Regulatory Commission via EIA.

OFAC SDN sanctions screen for a name / entity / wallet (?name=)

Live UK public-sector tenders from Find a Tender and Contracts Finder in one call. Returns the top 10 matching notices as one-paragraph plain-English briefs with buyer, value, deadline, CPV codes (honest null when the notice carries none) and the official notice link. Searches a 6-hourly refreshed index - no signup with either portal needed.

Cyre Intent Seal — hash your intent locally, seal it before you pay or sign, then match it on /api/receipt. Stops bait-and-switch. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Settlement Attestation. REQUIRES ?tx_hash= on the paid request — a signed request without it is refused before the gate and no money moves. A signed JSON observation of one transaction on Base, Polygon, or Solana — the identifier's shape picks the chain — with status (SETTLED, NOT_FOUND, PENDING_FINALITY, INSUFFICIENT_MATCH or REVERTED), block height (slots on Solana), confirmations, chain head, the query echoed back, and an evidence hash — verifiable against the store's pub…
